Abstract (en)

Disclosed is a space-time trellis code (STTC) encoding method for performing space-time coding of a serially-concatenated space-time code (SC-STC) in an encoder having an outer encoder for performing channel coding and an inner encoder for performing the space-time coding, in a mobile communication system including one or more transmission antennas, by transmitting via a first transmission antenna a symbol generated by encoding a first input signal output from the outer encoder by a first recursive convolutional encoder and a symbol generated by encoding a second input signal output from the outer encoder by a second recursive convolutional encoder; and transmitting via a second transmission antenna the first and second input signals.
